The two categories of behavior for C. pallida males are patrolling and hovering. These strategies are also used to find mates. In one category (the patrollers), male bees will patrol 3–6 centimeters above the ground in search of sites where buried virgin females will emerge. When a male bee finds such a site, he will dig 1–2 centimeters through the soil by gnawing at the surface with his jaws and using his forelegs to remove dirt from the excavation. If a female is found, he will attempt to mate with her either on the surface or at a nearby flower or tree. Other patrollers will sometimes attempt to steal a digging spot that another bee has found. If a bee has already found a female, another patroller bee may separate the male from the female so that it can copulate with the virgin. More often than not, the female (once found) will mate with either the male that found her or with an intruder.[6]

They are large (up to 3 cm), fast-flying bees, distinguished from the closely related genus Epicharis by the absence of long, whip-like setae that project backwards from just behind the eyes. They are commonly encountered bees in American deserts, and are active at very high ambient temperatures when many other species are in hiding. They can often be seen in large numbers on desert-willow (Chilopsis) and palo verde (Parkinsonia) blossoms. Bees of this genus are of some economical significance in pollinating crops such as Brazil Nut (Bertholletia excelsa) and Cashew (Anacardium occidentale, pollinated by C. tarsata among others).

The retirement of the Centris name was announced in September 1993,[2] with the 610, 650 and 660AV all being rebranded the following month as Macintosh Quadra machines as part of Apple's effort to reposition their product families to correlate with customer markets instead of price ranges and features. The IIvx was also discontinued in favor of the newly-announced Quadra 605.
The Centris 610 uses a 20 MHz 68LC040 CPU, which has no math coprocessor functions. It used a new "pizza box" case that was intended to be placed under the user's computer monitor. This case was later used again in the Quadra 610 and Power Macintosh 6100 lines of computers and, when these later computers were introduced, Apple offered consumers a product upgrade path by letting them buy a new motherboard. Apple's motherboard upgrades of this type were considered expensive, however, and were not a popular option. The Centris 610 also provided the base for the Workgroup Server 60. Chacun des propriétaires de terrain du projet Square Watson devra faire approuver les plans de la maison qu’il entend construire par le représentant du vendeur, soit par Luc Élias et préalablement aux travaux de construction. De plus, la couleur des revêtements extérieurs ainsi que celle de la toiture de la maison à être érigée doivent être approuvés par le représentant du vendeur, soit par Luc Élias. Une terrasse commune est aménagée sur le toit, au 6ème étage, avec un plan d’eau pour la baignade (piscine ou spa de nage). Ouverte sur trois côtés, cette terrasse offre la vue sur les Laurentides. Une aire de repas est aménagée et comprend un BBQ à la disposition des copropriétaires. Une salle d’exercices (gym climatisé avec exerciseurs) et une salle d'eau avec toilette et douche sont aussi aménagés dans une zone intérieure adjacente à la terrasse.
